Be it known that I, JAMES STANLEY, a citizen of the United States,residingat Newcastle, in the county of Henry and State of Indiana, have invented new and useful Improvements in Wind mills,of which the following is a specification. I

Y My invention relates to new and useful improvements in windmills; and its, object is to provide a'tower of novel construction, upon which is arranged a revoluble head in which is journaled a drive -shaft having a windwheel of novel construction secured thereto. Novel means are employed for imparting reciprocating motion to a pump-rod from the drive-shaft.

Another object of the invention is to mount the vane of the mill in such a manner as to permit the same to automatically throw the Wheel out of operative position in relation to the air-current and at the same time apply a brake to the wheel to retard and stop the rotation thereof.

With the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter more fully described andclaimed, and illustratedin the accompanying drawings, showing the preferred form of myinvention, and in which Figure 1 is a frontelevation of a windmill constructed in accordance with my invention.

Fig. 2 is an enlarged section through't-he head I of the windmill and showing the drive mechanism in elevation. Fig. 3'is a plan view of the head with the wheel and vane removed. Fig. 4 is a rear elevation of said head with the vane and wheel removed and with the weighted lever broken away, and Fig. 5 is a vertical transverse section of the head, showing the operating-gears in elevation.

The tower of the mill used in connection with my invention is preferably formed of sections 1, of metal tubing, connected by suitable joints 2 and so located as to form the cornor-standards of the tower. Cross-bars 3are oppositely screw-threaded at their ends and placed in engagement with the joints 2, and brace-bars 4 extend from these joints at angles thereto and have their inner ends threaded and inserted into flanges 5, formed .the casting 17 is slidably mounted.

Nuts

7 are arranged upon the ends of these rods 4 and serve to hold them securely in position within the flanges 5.

It will be understood that by constructing the tower in the manner above described it is unnecessary to employ bolts and screws as heretofore, and the tower can be constructed at less cost, but rendered more durable than those ordinarily employed.

A casting 8 is secured to the upper sections 1 of the tower, preferably by inserting the screw-threaded ends 9 of said sections into a flange 10 thereon, as shownin Fig. 2. Within this casting is revolubly mounted a tubular extension 11, projecting downward from the bottom-of the head 12 of the tower. Within this extension is slidably mounted a plunger 13, the lower endof which is connected to a pump-rod 14, while its upper end is connected, by means of a link 15, with an ear 16, extending downward from an oval-shaped casting 17, having cogs 18 upon the inner surface thereof. This casting is slidably mounted upon one side of the head 12 at a point directly above the plunger 13 and is held in proper position by means of a lateral extension 19, having a slot 20 therein, within which A strip 21 extends longitudinally of casting 17, at the center thereof, and is formed therewith or secured thereto in anysuitable manner. This strip serves to guide a lug 22, extending from the center of a gear 23, normally meshing with the cogs l8, and as the lug22 bears upon theguide-strip 21 it is obvious that the gear will be held securely in mesh with the cogs 18. The ends of the guide-strip are cut away, so as to permit the lug 22 to movelaterally when the cogs upon the ends of the'casting 17 are engaged by the gear.

-A gear 23 is secured to the inner end of a shaft 24, extending laterally through head 12 and this collar is adapted to be contacted by v a semicircular brake-shoe 32, arranged at one end of a bell-crank lever 33, which is pivoted to head 12. The other end of this lever 33 is connected, by means of a rod 34, to the tail 35 of a vane 36, and said tail 35 is pivoted upon a pin 37, which extends vertically from the outer edge of the extension 19 of the head to an car 38, formed adjacent to the bottom of head 12. As the rod 34 is pivoted to the tail 35 at a point in front of the fulcrum thereof, it is obvious that when the vane is swung upon its pivot motion will be imparted to bell-crank lever 33 by rod 34, and the brakeshoe will be moved from or into contact with the collar 31. The inner end of the tail 35 has an upwardly-extending lug 39, which is adapted to limit the movement of the vane in one direction, and an ear 40 extends from the tail 35 and is connected, by means of a spring 41, to a lever 42, which is fulcrnmed upon pin 37 and is connected at its opposite end to a rod 43. This rod is pivoted to an arm 44, extending downward from the fulcrum 45 of a weighted lever 46, and the inner end of said lever is connected to an operatingrope' 47, which extends downward from the head 12 to the base of the tower.

It will be understood that the spring 41 holds the vane 36 normally in alinement with shaft 24, and therefore in an ordinary wind the blades or wings 30 of the wheel will be held with their faces to the wind, thereby causing the wheel to rotate. A rotary motion of the wheel will cause the gear 23 to revolve, and as this gear meshes at all times with the sliding casting 17 it is obvious that said casting will be reciprocated back and forth, thereby imparting a reciprocating motion to the pump-rod 14. When the wind becomes too strong, the rope 47 can be loosened to permit the weighted lever 46 to drop. This movement of the lever will swing arm 44 inward and cause the arm 43 to swing the lever 42 upon its fulcrum, thereby releasing the tension of spring 41. The wind will thus swing the vane 36 upon its pivot and bring the wind-wheel in position with its periphery in the path of the wind. At the same time rod 34 will be moved longitudinally by the tail 35 of the vane, and bell-crank lever 33 will be swung'upon its fulcrum to bring the shoe 32 into contact with collar 31, thereby preventing the rotation of the wheel. When the rope 47 is pulled downward, the lever 46 is raised and the operation of the parts above described is reversed. As soon as spring 41 is tensioned lever 46 will be moved back thereby into alinement with shaft 24.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as new is--- 1. In a windmill, the combination with a tower having a revoluble head thereon; of a shaft journaled within the head, means for transmitting reciprocating motion from the shaft to a pump-rod, a wheel secured to the shaft, a vane pivoted to the head, a lever pivoted to the head, a spring connecting the lever and vane and adapted to hold said vane normally in alinement with the shaft, a weighted lever and a rigid connection between said lever and the lover of the spring whereby the tension of said spring may be regulated.

2. In a windmill, the combination with a tower having a revoluble head thereon; of a shaft journaled within the head, means for transmitting reciprocating motion from the shaft to a pump-rod, a vane pivoted to the head, a lever pivoted to the head, a spring connection between said lever and the vane, a weighted lever, an operating-rope connected thereto, and a rod connecting said lever to the lever of the spring whereby the tension of said spring may be regulated.

3. In a windmill, the combination with a tower having a revoluble head thereon; ofa shaft journaled within the head, means for transmitting reciprocating motion from said shaft to a pump-rod, a wind-wheel secured to the shaft, a vane pivoted to the head, a brakeshoe adapted to contact with the shaft, 9. bellcrank lever connected thereto, a rod connecting the lever to the vane, a lever pivoted in the head, a spring connecting said lever and vane, a weighted lever, a rod connecting said weighted lever and the lever of the spring, and an operating-rope connected to the weighted lever.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES STANLEY.
